All Trigonometry Functions
The important trigonometric functions include sin and cos, as all the other trigonometric ratios can be defined in terms of sin and cos. The six important trigonometric functions (trigonometric ratios) are calculated using the below formulas.
Functions | Abbreviation | Relationship to sides of a right triangle |
---|---|---|
Sine Function | sin | Opposite side/ Hypotenuse |
Cosine Function | cos | Adjacent side / Hypotenuse |
Tangent Function | tan | Opposite side / Adjacent side |
Cosecant Function | cosec | Hypotenuse / Opposite side |
Secant Function | sec | Hypotenuse / Adjacent side |
Cotangent Function | cot | Adjacent side / Opposite side |
Trigonometry in Maths: Table, Formulas, Identities and Ratios
Trigonometry is a branch of mathematics that explores the relationships between the ratios of the sides of a right-angled triangle and its angles. The fundamental ratios used to study these relationships are known as trigonometric ratios, which include sine, cosine, tangent, cotangent, secant, and cosecant.
The term “trigonometry” is a 16th-century Latin derivative and the concept was given by the Greek mathematician Hipparchus. Trigonometry word is formed from ancient Greek words “trigonon” and “metron” which mean triangle and measure respectively, thus collectively called Trigonometry which means measures of a triangle.
The most important topics in trigonometry are trigonometry table, trigonometry formulas, trigonometric identities, and trigonometric ratios. In this article, we will see the basics of trigonometry, including its fundamental identities and formulas.
